\VILLIAM H. PRINZ, OF AUSTIN, ILLINOIS, ASSIGNOR TO THE SALADIN PNEU- MATIC MALTING CONSTRUCTION COMPANY, OF CHICAGO, ILLINOIS.

APPARATUS FOR DRYING MALT.

SPECIFICATION forming part of Letters Patent No. 626,929, dated June 13, 1899.

Application filed August 15', 1898. Serial No. 688,621. (No model.)

To all whom, it may concern.-

Be it known that I, WILLIAM H. PRINZ, a citizen of the United States,residing at Austin, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Apparatus for Drying Malt; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a novel construction in an apparatus for drying malt, the object being to provide a device of this character of simpler and more compact construction and simplicity and efficiency of operation than present devices of this character; and it consists in the features of construction and combinations of parts hereinafter fully described and claimed.

In the accompanying drawings, illustrating my invention, Figure 1 is a fragmentary'vertical transverse section of an' apparatus for drying malt constructed in accordance with my invention, taken on the line 1 1 of Fig. 2. Fig. 2 is a fragmentary vertical longitudinal section of same on the line 2 2 of Fig. 1. Fig. 3 is a transverse vertical section of a modified form of construction on the line 3 3 of Fig. 4. Fig. 4is a vertical longitudinalsection of same on the line a 4: of Fig. 3.

In malt-driers heretofore constructed and covered by several patents granted to me I provided a mixing-chamber for mixing the hot and cold air, situated immediately above the furnace-outlet, such air passing thence horizontally toward the ends of said chamber and thence through openings in a floor above said furnace which formed a hopper-floor. This construction is expensive and requires a high building.

My present invention has for its object to obviate the necessity of providing such additional floor, thereby greatly reducing the cost of construction and enabling the use of a building fully twenty feet less in height than was heretofore required.

In the drawings, A indicates a furnace provided with a plurality of grates or fireplaces, each separately walled in and placed side by side on the ground-floor of the building and alternated with spaces B, into which cool air is admitted through the blinds or slats 1. Said furnace has its outlet above a floor 0, which surrounds said furnace atii's upper end and extends from the outer walls thereof to the walls of the building. The end walls D of said furnace A are continued above said floor 0 and are continued lengthwise on said floor to the end walls of the building, thus dividing said floor G into three compartments, extending the entire length of the building. Said walls D are provided along their upper edges with recesses 2 at intervals, and on said 'upper edges support a hood 3, said recesses 2 forming openings below said hood 3, through which the heated air is adapted to pass. Mounted between said walls D, below said recesses 2, is a horizontal partition 4, extending the entire length of said building and separating the heating from the drying chamber. Said partition 4 is provided at intervals with valve-controlled openings 5, through which and the recesses 2- the hot air is adapted to pass into the drying-chamber 6, in which one or more drying-floors 7 are contained. In this manner I form a mixing-chamber 8 between said walls D, in which the hot air from said furnace A and the cold air entering through the slats or blinds l are adapted to mix before passing into the drying-chamber 6. To prevent the direct passage of the hot air from the furnacethrough said openings 5, deflectors 9 are mounted above said furnace. Besides obtaining said mixing-chamber 8 between said walls D, I obtain spaces or receptacles 10 on each side of said mixing-chamber, which are adapted to receive hoppers 11, into which the malt from the drying floor or floors is dumped.

As will be obvious from the above description, I save a great deal of space by means of the arrangement described, as well as the expense of an additional floor and the greater height of building which would be required in consequence of said additional floor. I also effect such saving without in any manner reducing the efficiency of the drier or complicating the operation of the same.

In Figs. 3 and a I have illustrated a modified form of construction in which a cylindrioal vessel 12 is mounted upon the floor O and is connected with the furnace, thereby serving as a mixing-chamber.

I claim as my invention 1. In an apparatus for drying malt, the

combination with a furnace, a floor surrounding the delivery end of same, and means for admitting cold air above said floor, of walls dividing said floor into a plurality of com- ,partments, one of which communicates with said delivery end of said furnace and is covered by means of a horizontal partition ex-- tending between said walls, thereby forming a mixing-chamber for the hot and cold air admitted to said compartment, and valve-controlled openings establishing communication between said mixing-chamber and the dryingchamber above the same, substantially as described.

2. In an apparatus for drying malt, the combination with a furnace, a floor surrounding the delivery end of same, and means for chamber and the drying-chamber above the same, substantially as described.

3. In an apparatus for drying malt, the combination with a furnace and a floor surrounding the delivery end of same, of walls dividing said floor into a plurality of compartments, one of which communicates with said furnace and is covered by a horizontal partition having openings therein at intervals, and a hood mounted above said partition, and said other compartments being adapted to serve as receptacles for malt, substantially as described.

4. In an apparatus for drying malt, the combination with a fn rnace, a floor surrounding the delivery end of same, and means for admitting hot and cold air above said floor, of walls dividing said floor into three compartments of which the middle compartment communicates with said furnace and forms a mixing-chamber for the hot and cold air, a covering over said middle compartment, valve-controlled openings in said covering, and a hood above said covering adapted to serve as a guide for falling malt to lead same into the side compartments which serve as malt-receptacles, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.
